Mardy Fish appeared sluggish, agitated and uninspired on Wednesday at the Australian Open in a four-set loss to Colombia’s Alejandro Falla, falla-ing 7-6(4), 6-3, 7-6(6).

“It’s my responsibility to put it behind me, you know, but I’m a human being,” said Fish on being bothered by Falla repeatedly asking for the trainer. “I see that guy’s called the trainer three, four times, however many times he was out there. It’s hot. And I;m down two sets to love, and I’m looking for anything to sort of gain the momentum a little bit…I didn’t get angry with the chair umpire. Just asked him how many times the guy is allowed to come for cramps.”

No. 16 seed John Isner survived a match point in a five-set win over David Nalbandian, triumphing 10-8 in the fifth.

“It was a lot of fun, first off,” Isner, who had to overcome cramping in the fifth set, said of the marathon match. “Very similar to my match here last year where I lost 9-7 in the fifth on that same court. So I tried. I told myself I didn’t want to repeat that effort. I wanted to actually win that one. It felt really, really good to win it.”

Unseeded Aussie teen Bernard Tomic continued his roll on Wednesday, losing the first set but defeating American Sam Querrey in four.

“The first set was very strange,” Tomic said. “He played very good, and I started questioning myself if he’s going to keep serving and playing like this whether I have a chance. But I got lucky, and he didn’t serve as good in the second. He gave me confidence.”

On the women’s side No. 10 seed Francesca Schiavone was tripped-up by an Italian countrywoman who knew her game well when Romina Oprandi beat the former French Open champ 6-4, 6-3.

Other upset victims were (16) Peng Shuai, who lost in straights to Czech Iveta Benesova, and (32) Petra Cetkovska, who fell to the hot-handed German Mona Barthel in straights.

“It’s just a small blister,” said Wozniacki on dealing with a foot issue during the match. “It was good just to tape it up and make sure that it was okay…I thought the first set I played pretty well. I stayed aggressive and made her run. Second set, she went a bit more for her shots, and I stepped back a little bit and she punished me for that.”

Well, I’m sorry for Kimberly’s little guy that Fish lost, but other than that I don’t care too much! He was a brat out there! And there was that recent incident with Dimitrov, too. Can we please have one high profile American who doesn’t throw tantrums on court?

I haven’t heard anything bad about Jack Sock, not yet. He is not high profile but there is hope for non-tantrum-throwing Americans in the future.

If you can tolerate the atrocious, mind numbing and stupid dress sense, Venus is not bad. She evens the family tantrum factor.

Yeah, Humble Rafa, Venus does not throw tantrums, but she is on the way out. I hope Jack Sock is able to make it big! I saw an interview with young American Sloane Stephens and she seems like a totally lovely person — hope she can make it, too!

Thank you for including Wozniacki among those who “cruised.” It’s amazing how negative the TV commentators have become about anything she does. The girl was serving at 4-5 40-15 in the second set after winning the first, and was described as being in a world of trouble by Pam Shriver. Anyone else would have been described as being on serve.

Nadal is showing some good positive signs on the court! He is hitting his shots with more power and aggression. His movement has also become better. If we look at his stats from 2011 and this year so far (Rafael Nadal- Early Signs Of Improvement! http://bit.ly/wvSe0f ), he is playing better and winning more % points on his first serve.

As Andre Agassi once said that if you can keep you unforced errors between 5-10 at AO in each set, you have a good chance of winning the set. Nadal seems to be following it with just 31 unforced errors so far in this tournament. Good sign for Rafa camp!

..nothing new ..very rafa like and he will cruise to the semis where roger will wait and i dont expect much of that encounter because every star lines up in his favour in GS matches (at least the last 3-4 gs matches they played )so i dont care anymore

that horrible (rafa)party playing that same old song is going to be spoiled by the djoker !!!!!

@Lou, I am worried that he is still hitting the shortballs which allows the opponent to hit outright winner on DL or crosscourt…espn2 illustrated this in yesterdays match…Hass was hitting good winners which I beleive because of Rafa’s previous short ball that lands in opponents comfort zone.

Ferrer has won. ESPN has once again covered an obscure American with a dull game, only to see him lose.

Congrats to Kvitova, she is a tough cookie and she definitely knows how to win. I do feel for Suarez Navarro, she’s been constantly injured for much of the last couple years. I wish she could play a full season for once, that game is just too beautiful to go to waste.

Hi mat4, :) just heading off to sleep, but yes, I caught about the last half of Nole’s match and he was playing very well: precise, sharp, and fast. With some nice variety, too, saw one great lob, drop shots, volleys, all mixed in with the usual baseline onslaught. He served fairly well, though perhaps not enough firsts in. But he was winning a large percentage of firsts and seconds too. He says he’s been working on placement (not necessarily power) with regards to the serve. Must be off to sleep, perchance to dream. Talk soon.

Djokovic won easily today. Pretty easy win. The way he is playing-looks like he will reach easily to SF.Its good to see him trying to improve his game like trying to come to net more often and drop shots.
I read this article on his interviews since 2007 and saw how he has gradually achieved his goals so far! Very very inspiring. Evolution of Novak Djokovic- Australian Open (2007-2012)! http://bit.ly/xO8U7D
